Pizzazz from legislator wearing nothing? Golly! (5)
I believe the answer is:
oomph
'pizzazz' is the definition.
(I know that pizzazz can be written as oomph)
'from legislator wearing nothing? golly' is the wordplay.
'from' becomes 'o' (I've seen this in other clues).
'legislator' becomes 'MP' (an MP legislates in parliament).
'wearing' indicates putting letters inside.
'nothing? golly' becomes 'oh' (I can't explain this - if you can you should give a lot more credence to this answer).
'mp' going within 'oh' is 'omph'.
'o'+'omph'='OOMPH'
Can you help me to learn more?
(Other definitions for oomph that I've seen before include "Shows excitement aplenty" , "Dynamism" , "Vitality, zing" , "Go" , "Enthusiasm - vigour - sex appeal" .)
